Step-by-step explanation:
The relative dispersion of a data set is the ratio of its standard deviation to its arithmetic mean.
Mr. and Mrs. Jones' neighborhood mean family income is $45,000 with a standard deviation of $9,000.
Their Relative Dispersion is given as:
Standard Deviation: Mean
9000:45000
1:5
Expressed as a Percentage: (1/5)x100=20%
The Relative Dispersion of the family incomes in Mr. and Mrs. Jones' neighborhood is 20%
Mr. and Mrs. Smith's neighborhood mean family income is $100,000 and the standard deviation is $30,000.
Their Relative Dispersion is given as:
Standard Deviation: Mean
30000:100000
3:10
Expressed as a Percentage: (3/10)x100=30%
The Relative Dispersion of the family incomes in Mr. and Mrs. Smith's neighborhood is 30%
